Smooshed diamonds: A window into exoplanets?
Scientists have compressed diamonds more than ever before. Their carbon may give clues to what conditions might be like deep within planets way beyond our solar system.

Mega-bird!
What may have been the bird world’s biggest flier ever had wings so long, they would have had trouble flapping fast enough to keep it aloft in tough winds. But this behemoth would have been able to soar both far and fast.

Quark quartet forms exotic particle
Quarks are important building blocks of matter, usually bound together as pairs or triples. Now some have formed a quartet. Scientists confirmed the existence of a particle made of four quarks stuck together. Such strange stuff may have been more common in the earliest universe, the scientists say.

Dead star makes a lens for its companion
Much like the lens on a camera, the intense gravity of a newfound white dwarf bends light. In this case, it is distorting light emitted by the star it orbits.

World’s coolest ‘clock’ is also crazy-accurate
This is the time to beat — the world’s most accurate atomic clock ever. At its heart is a ‘fountain’ of cesium atoms chilled nearly to absolute zero!
